The PA31ER power adapter from Chauvin Arnoux is a specific accessory for the Qualistar power analysers in the C.A 833X model series. It enables direct power supply to the measuring device via a mains phase conductor, eliminating the need for a socket. This is particularly advantageous for measurements in industrial environments or during extended recording periods, where continuous power supply is required. The adapter uses the voltage inputs of the analyser to power the device and simultaneously charge the battery, allowing the measurement to continue for the remaining battery runtime in the event of a power failure.

Applications

The power adapter is designed for use in demanding environments, particularly where no socket is available or where a mobile, independent power supply is required. It is suitable for industrial plants, energy distribution networks, and other areas where the C.A 833X power analysers are used. The IP53 protection rating ensures sufficient protection against dust and splashing water, enabling use in outdoor environments or damp indoor areas.

Functions and Equipment in Detail

The adapter features two cables with axial sockets, which are connected to the voltage inputs of the power analyser. It can handle voltages in the range of 100 V to 1000 V AC or DC, enabling broad applicability in various electrical systems. The direct supply via the voltage inputs ensures that the device can continue operating even during interruptions in mains voltage, as long as the battery is charged.

Technology Explained Simply

The input voltage range of 100 V to 1000 V AC or DC allows the adapter to be used with various voltage sources, regardless of whether they are alternating or direct current. The safety category according to IEC 61010 (CAT III 1000 V / CAT IV 600 V) guarantees that the adapter is suitable for measurements in electrical installations with the corresponding voltage class. The IP53 protection rating means the adapter is protected against dust and splashing water, making it suitable for use in environments with increased contamination or moisture exposure.

Compatibility and Accessories

The PA31ER power adapter is specifically developed for the Qualistar power analysers in the C.A 833X model series, including models CA8335, CA8331, CA8333, and CA8336. It is not a universal accessory, but requires the specified devices for proper function. The connection is made via the voltage inputs of the analyser, enabling direct power supply and simultaneous battery charging.

Installation and Mounting

Installation is carried out by connecting the two cables with axial sockets to the voltage inputs of the power analyser. It is essential to ensure that the voltage is within the permissible range of 100 V to 1000 V AC or DC. The operating manual, included in the delivery, contains instructions for safe use and installation.

Operational Advantages

Using the PA31ER power adapter enables independent power supply for the power analyser, increasing the device’s flexibility and operational duration. Simultaneous battery charging ensures the device can continue operating during a power failure. The IP53 protection rating and IEC 61010 safety category enhance reliability and safety when used in demanding environments.
